CL-Out bioaugmentation was implemented following ISCO treatment of TCE-contaminated ground water. Through bioaugmentation the ground water remediation was complated and ground water conditions were restored in 30 days.

BackgroundThe chlorinated solvent trichloroethylene (TCE) was discovered in ground water at a manufacturing facility in eastern Massachusetts. ISCO was selected for remediation of the ground water. Although ISCO reduced TCE concentrations, the residual post-ISCO TCE concentrations were above the applicable remediation standards. The environmental consultant chose CL-Out® bioaugmentation to treat the residual ground water contamination. The CL-Out® treatment successfully achieved the remediation goal quickly and at a low cost.
